For rim burn, the best tactic is prevention. Don't fully load the chamber & use a flame
that either must be drawn down into the chamber or can be directed into it. In dealing with
Meerschaums that have been burnt, Beeswax will help to dissipate the discoloration, but to
remove it, you will have to sand and re-wax it. The accumulation of smoke tars, a bit of
saliva on a clean white cotton cloth will help keep this to a minimum with routine maintenance.
